Visual audit of steel structures and civil works at Beeshoek North and South Mines in the Northern Cape.

The North Mine previously supplied all of Assmang’s iron ore output since 1964. A series of large-scale infrastructure projects had maximized efficiency and productivity on site, which included a full washing and screening plant and a jig plant to beneficiate off-grade ore. Assmang commissioned Beeshoek South Mine in 1999.

The various structural elements were each allocated a condition category ranging from 0 to 5 (0 signifying excellent condition and 5 little to no useful residual strength), followed by priority level recommending the required remedial action.

Woolworths Table Bay Mall

Cape Town
2016

Properties

Table Bay Mall is new shopping centre of 65 000m² expected to be completed in October 2017. Table Bay Mall is the 2nd largest after Mall of Africa. Underfloor heating is the most comfortable form of heating. It is unobtrusive, economical, safe, hygienic and virtually maintenance-free. It offers the best long-term method of heating a building because it uses low-temperature water.

Woolworths has embarked on installing water based underfloor heating in all its new stores in the food trading area. The under floor heating for Woolworths Table Bay Mall is designed to keep the Food Trading Area room temperature at 20 °C and floor temperature at 24°C

BVi have designed the system to maintain 20°C room temperature in the food trading area.

The project entails the construction of 6 buildings of 4 storeys each, consisting of 2 bedroom and 3 bedroom apartment blocks. The project commenced in July 2016, and will run for 18 months. The project is currently 20% complete.

Detail design and construction monitoring of the replacement of foundations, structures and small part steel for its 3kV lines that are in need of replacement.

The project is divided into 5 Phases, spread out across 20km of railway tracks between various stations in the Cape Town area. The phasing is based on commuter volumes on the railway system and extent of corrosive decay of the steelwork observed on site.

Various types of structures at typical 67m spacing along the rail tracks suspend the electrical wires for the trains.

The appointment includes the survey of the existing infrastructure to identify the structures due for replacement. Structures with a rating of 2 or lower were allocated for replacement on more than 500 locations spread out over the 20km of railway track.

A contractor from Gauteng was appointed on a 2 year contract to the value of R80m to replace the structures. The contractor fabricates the steelwork in Gauteng and galvanizes and paints the steelwork with a Duplex paint system. All the steelwork is then transported by truck to Cape Town for erection under Permit conditions at night. Works started in July 2016 and is planned for completion in July 2018.

2015

Public Sector

Phase 1

The primary objective of the first phase was to repair the failing plaster/grano façade of the building. This became a threat to pedestrian and vehicle traffic. This phase consisted of the removal and subsequent major concrete rehabilitation to an area of 28 400m². Use was made of external scaffolding supported on a reinforced concrete canopy over the sidewalk. This structure served as a scaffold support as well as safety for the pedestrians not to interrupt the building functionality. It is to be noted that the scaffolding was to the full 26 storeys – the highest used in the Southern Hemisphere.

Phase 2

The second phase was for additional facilities, basement parking, upgrading of the present Keerom Street walk-through to a functional and friendly pedestrian area with a restaurant and other public facilities.

Durham Square Residential Development

Orcinus Properties
Salt River, Cape Town
2008

Properties

The project consisted of 7 residential floors, 3 parking floors and a basement for commercial use. The soil conditions on site were unstable due to heaving and collapsible red clay, which meant that the foundations had to be piled. The building was designed to have flexible joints between columns and balustrade beams to allow for possible soil settling or heaving. The residential floors have 16m wide balconies cantilevering 3m. These large curved balconies largely contributed to the aesthetic appeal of the building and could therefore not be supported at the lower level. A unique tie system was introduced in the partition walls using a tension/compression system between the slabs all the way to the roof to support the cantilever balconies.

Rehabilitation of Skoenmakers River

The project is about conducting feasibility studies on river structures and investigation on the Skoenmakers River which has been utilised as a conveyance system and spillway to Darlington Dam since 1981. The feasibility studies are necessitated by deterioration of the river channel over the years which have resulted in the erosion of the river embankments, creation of an island in the river bed, loss of vegetation, erosion of some bridge-supporting embankments and transportation of vegetation and silt downstream. Investigate the impact of water releases down the river bridge and compilation of a river rehabilitation strategy to improve access across the river and to halt further degradation of the river.

The aim of the assignment is to assist the National Water Resources Infrastructure (NWRI) in understanding the impact of water release down the Skoenmakers River in an effort to have intervention measures put in place to upgrade the river bridge structures and prevent further deterioration of the river embankments and bed to minimise the loss of human lives, livestock and wildlife in the area.
